[0028] As Figures 1 - 2 shown, the present utility model is a fitting degree detection mechanism, including an air detection seat. An air detection hole vertically penetrates through the air detection seat. An air detection valve core 3 slides vertically in the upper part of the air detection seat. An elastic element is provided between the bottom of the air detection valve core 3 and the air detection seat. An air detection seal ring 4 is installed in the air detection hole. A sealing convex ring 3-1 is provided in the middle of the air detection valve core 3.

[0029] The air detection seat adopts a split structure and is composed of an air detection upper seat 2 and an air detection lower seat 1. Specifically, the air detection upper seat 2 and the air detection lower seat 1 are connected by a threaded structure; an external threaded structure is provided at the lower part of the air detection upper seat 2, and a matching internal threaded hole is provided at the upper part of the air detection lower seat 1. To ensure the airtightness between the two, a seal ring 5 is inlaid on the top surface of the air detection lower seat 1, and the bottom of the air detection upper seat 2 abuts against the seal ring 5.

[0030] The air detection hole is composed of a lower air detection hole 1-1, an upper air detection hole 2-1, and a side air detection hole 2-2 that are connected. The lower air detection hole 1-1 vertically penetrates through the air detection seat. The upper air detection hole 2-1 vertically penetrates through the air detection upper seat 2. The side air detection hole 2-2 is horizontally located in the air detection upper seat 2. The top of the lower air detection hole 1-1 is communicated with the bottom of the upper air detection hole 2-1. The upper air detection hole 2-1 is communicated with the inner end of the side air detection hole 2-2. A sensor (not drawn) is installed at the outer end of the side air detection hole 2-2.

[0031] The air inspection sealing ring 4 is embedded in the upper air inspection hole 2-1, below the inner end of the side air inspection hole 2-2.

[0032] Such as Figure 4 As shown, a limiting convex ring 3-2 is provided at the upper part of the air inspection valve core 3, and a matching limiting step hole is provided at the top of the upper air inspection hole 2-1. The two cooperate to limit the upward movement of the air inspection valve core 3.

[0033] The upper part of the lower air inspection hole 1-1 is a stepped hole structure for positioning and placing the lower part of the elastic element. The upper part of the elastic element abuts against the air inspection valve core 3.

[0034] The elastic element is a spring 6.

[0035] The specific specification of the air inspection sealing ring 4 is: an O-ring with a size of 4x1mm.

[0036] The specific specification of the sealing ring 5 is: an O-ring with a size of 10x1.9mm.

[0037] The working process of the present utility model is as follows:

[0038] Such as Figure 2 As shown, in the non-working state, the spring 6 pushes the air inspection valve core 3 to extend upward out of the upper air inspection seat 2; the sealing convex ring 3-1 is located above the air inspection sealing ring 4, and the two do not contact. The air inspection hole is unobstructed, and gas is introduced into the bottom of the lower air inspection hole 1-1, and the sensor can sense the gas in the side air inspection hole 2-2.

[0039] Such as Figure 3 As shown, during work, the workpiece is placed on the top of the upper air inspection seat 2, and the workpiece pushes the air inspection valve core 3 downward, and at the same time, the spring 6 is compressed by force. Since the gravity of the product is greater than the elastic force of the spring 6, the product will be flush with the upper air inspection seat 2. At this time, the sealing convex ring 3-1 descends to contact the air inspection sealing ring 4, the air inspection hole is unobstructed, the sensor cannot sense the gas in the side air inspection hole 2-2, and the product is in an ideal flush state with the surface of the reference seat.

[0040] When the product is deformed or there is a foreign object on the top of the upper air inspection seat 2, the product and the upper air inspection seat 2 cannot be in complete contact, resulting in the air inspection valve core 3 not being able to be completely pressed down, and there is a relative gap between the product and the surface of the upper air inspection seat 2. At this time, the sealing convex ring 3-1 is located above the air inspection sealing ring 4, and the two do not contact. The air inspection hole is unobstructed, and gas is introduced into the bottom of the lower air inspection hole 1-1, and the sensor can sense the gas in the side air inspection hole 2-2.

[0041] It should be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principles of the present utility model. However, the present utility model is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present utility model, and these modifications and improvements are also regarded as the protection scope of the present utility model.
